We begin with the midlatitudes, where the meridional cells are mechanically
driven (see below) by turbulence, similar to Earth's Ferrel cells,
which form as a consequence of atmospheric waves breaking in midlatitudes
[1]}. Unlike the largely baroclinic midlatitudes of
Earth, which result in mostly non-mass-transporting Ferrel cells [2]}, [1]},
the predominantly barotropic flows on Jupiter (at the depth range
associated with the MWR measurements) [4]}, [5]}, [6]}
may allow mass-transporting meridional cells (see SI). Consistently, deep convection models of Jupiter also show barotropic flows [7]}, [8]}. The upper branch
of Earth's Ferrel cells consists of a balance between the Coriolis
force and the eddy momentum flux convergence,
\(-f\bar{v}=-\frac{\partial \left(\overline{u^{^{\prime }}v^{^{\prime }}}\right)}{\partial y},\)
